The exchange was among numerous internet chats prosecutors offered to support charges that Valle conspired with others online to kidnap, rape, kill and eat women he knew.

Also charged with illegally accessing a government database to research potential victims, Valle could face life in prison if convicted.

No women were injured and defence lawyers have argued he was merely fantasising with no intent to harm.

For two days, Walsh has testified about chats Valle had last year with a New Jersey co-defendant and two alleged co-conspirators: a man in Great Britain and Khan.

In several emails read by Walsh, Valle seemed eager to make the woman he would marry a few months later an offering of sorts to Khan, though he added: "She is a sweet girl. I like her a lot. But I will move on."

Valle wrote that he could talk her into going on a trip to India before they took her to Pakistan, where they could gag her and take her to a basement, where they could hang her from her feet and take turns sexually assaulting her before slitting her throat and cooking her.

"I just love the thought of stringing her upside down," Valle wrote in an email shown to the jury.

He also said he would like "to see her suffer" and "slowly roast her until she dies."

Later Valle began discussing plans to attack a 27-year-old Ohio woman he knew in college.

He wrote that her death would "definitely make the news" and there would be "plenty of suspects" because she was a prosecutor.

The woman, Andria Noble, testified on Monday that she never knew Valle to be violent when they were at the University of Maryland together.

Baum was aiming to show little or no distinction existed between chats or emails the FBI deemed real evidence of a crime and those dismissed as fantasy.

Walsh conceded that no women were kidnapped or harmed and Valle never had contact with his supposed co-conspirators outside the internet.

No evidence of a crime was found in Valle's apartment besides a computer.

If jurors are offended or horrified by the gruesome testimony, they haven't shown it. Three of them even yawned.

Valle's wife, Kathleen Mangan-Valle, 27, has testified that she fled their New York City home in September with their baby daughter after discovering that Valle spent hours at night on extreme sexually violent websites.
